The EF 200-400 mm f / 4L IS USM lens with Canon's internal 1.4x extender is a high performance super-target zoom lens with a built-in 1.4x extender that converts the focal range and maximum aperture to 280-560 mm f / 5.6. The extender is located at the base of the lens and is applied with a simple toggle switch

Image Stabilization

The Lens Image Stabilization system provides four vibration correction stops, providing sharper images when shooting in low-light situations, when its position is uncertain, or when fast shutter speeds cannot be obtained. This lens has three stabilization modes: Standard, Panoramic, and Exposure Only modes. Standard mode (Mode 1) compensates for vibrations in all directions and is effective when shooting static subjects; Pan mode (Mode 2) corrects for vertical or horizontal jolts depending on the orientation of the camera, and is best when the camera is oriented to correct for vertical or horizontal jolts, and is best when the camera is moving,

Fast and accurate autofocus

With an internal focusing system, ultrasonic motor (USM), high-speed CPU and optimized AF algorithms, the 200-400 mm f/4L provides fast, smooth and accurate autofocus for use in a variety of applications.

Focus distance range

You can set the focus limitation range to three different ranges for faster and more accurate autofocus. The three ranges are: Full (6.56' to infinity); 6.56 to 19.69'; 19.69' to infinity.

Energy focus mode

Using the playback ring, the Power Focus mode allows smooth and automatic focus changes, which are essential when using EF 200-400mm f / 4 for movie making. Two speeds are available in the Power Focus mode.

It is possible to set a preset focus distance and return to it immediately at any point while in AF, PF, or MF modes with a simple left or right turn of the playback ring.

AF stop button

The four AF stop buttons located on the front grip ring allow you to temporarily stop autofocus.

Fluorite and UD Lens Elements

One fluorite and four UD (Ultra-low Dispersion) lens elements correct chromatic aberrations and provide sharp images throughout the zoom range.

Lens coating

Optimized lens placement and coatings provide outstanding color balance while helping to minimize ghost images and eruptions.

9-leaf circular opening

The 9-leaf circular aperture design helps provide beautiful, soft bottoms.

Tripod Mount

The lens incorporates a rotating tripod stand and, by loosening the tripod stand orientation locking knob, you can rotate the camera to obtain horizontal or vertical images without removing it from the tripod.

Drop-In filter holder

The lens includes a built-in 52 Series (WII) filter holder and allows you to place pre-cut gelatine filters sold separately at the rear end of the lens for specific applications.
